CHURN.

SPECIFICATION forming part of Letters Patent No'. 230,405, dated July 27, 1880. Application nien April 3o, ieee. (No mona.)

A enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters ot' reference marked thereon, which form a part of this specilication..

This invention relates to improvements in rotary-body churns 5 and it consists in the construction and arrangement ofthe several parts, hereinafter described, and pointed out in the claims. v.

In the drawings, Figure l is a vertical longitudinal section, and Fig. 2 is a vertical crosssection, of the body of a churn having my improvements attached thereto, and Figs. 3 and`V` 4 are detail views of the air-pipe.

a is the body, which is provided with trunuions a a2, and supported in a suitable frame.

The body may be made of any suitable form.

On the ends a3 of the box I place a series of breakers, b, which are arranged radially, or nearly radially, to axis of motion of the body. It' a round body be employed the breakers would be on the radial lines, but when a polygonal body is employed I prefer to place them at right angles to the sides and slightly off from the radial lines, as will been seen by reference to the positions shown .in Fig. 2.

The breakers have one side beveled'and the end rounded, as shown, while the opposite side is left straight and vertical to the plane of the endas. The breakers throw the milkl away from the ends a3. Y

c c c are a series of longitudinally-hinged tlappers or breakers, which areplaced on the inner periphery or sides of the box and parallel with the axis ot' motion. They are arranged alternately with the breakersb, and are provided with pins, which are held in guides d cl.v They turn freely on the pins, and will assume a position at right angles to or will lie flat against the sides ofthe body, as shown.

Fixed between the guides d d, and close to the tlappers, is a beveled strip, d', which serves as a stop or shoulder to keepl the flapper from turning entirely over. The guides d are arranged in pairs, there being a pair for each ilapper, and a guide at each end of said flipper,

and they have their ends d2 extended and flared outward from the liapper d, so that their ends are carried to a line or pointjust in rear ofthe vertical side of the end breakers, b, while their points Z3 are beveled on their outer sides. next the end of the body, so that they will throw the milk outward from the vertical center of the body.

The L-shaped tube e is for providing the necessary aeration. Its stem e is passed through the trunnion a', while its stem e2 is within the churn and is pressed against or very close to the end a3. The stem e2 has its ends closed, while its outer end,.e, has made through its side a small opening, e4, which is partially closed by a tongue, e5, bent inward, with its outer end near to the closed end e3, and just behind the lip e6. The opening e4 is covered by shield e7, so arranged as to permit the air or gas to pass freely between it and the stem e2. This peculiar construction of the tube permits 'the free passage of air-or gas for all required purposes, and at the same time prevents the milk from getting into the tube. The shield e7 forms a passage-way, open at both ends, so that any milk which may enter at one end will be thrown out by the rotary motion of the churn, and, acting in combination with the tongue e5, furnishes a perfect guard for the pipe e2.

In the operation of the device the box is turned in the direction of the arrows, Fig. 2. Thercream is thrown by the guides d and flappers c laterally against the ends of the body, and behind and against the straight vertical sides of the breakers d, which in turn throw it back toward the vertical center, and to be caught by the next pair of guides, by which it will again be thrown laterally, as in the first instance.

The tlappers or hinged breakers c rise to the vertical position shown in Fig. 2 .when the box is turned in the direction of the arrows. When the motion of the body is reversed these hinged breakers lie down flat against the sides, as shown in the upper part of Fig. 1.

After the cream is churned the motion of the body is reversed, and the beveled sides of the breakers b and the inward incline of -the guides d will gather all the butterinto a lump at the center, from which it can be easily taken.

' After the butter and milk have been removed, and water has been poured into the body, the action of the breakers b, guides d, and hinged flappers or breakers c will wash every particle of milk 'out of the chamber.

I am aware that in the construction of rotary-body churns it is not new to construct one of its trunnions hollow, so that an aerating tube may be placed therein and revolve with the churn, nor is it new to form the said aerating-tube in the form ot' an L, one wing of which is placed in the hollow trunnion, while the other wing lies inside of and close to the end ofthe churn, and has its open inner end bent over so as to give it a U or bracket shape; nor is it new to construct working-body ehurns with breakers which are tapering or inclined and arranged on the sides thereof7 and I do not claim such constructions; but,

Having thus described lny invention, what I claim, and desire to secure by Letters Patent, is-

1. In a rotary-body churn, the series of breakers b, fixed on the end boards, a3, and arranged radially to the axis of motion, the lappers c, hinged to the sides and parallel with the axis of motion of the body and arranged alternately with the breakers b, and the flaring guides d, arranged in pairs and at opposite ends of the fiappers c, and stop d', all arranged to operate substantially as and for the purposes set forth.

2. In a rotary-body churn,the L-tube e, having one ot its stems put through the hollow trnnnion a', and having its inner stem, e2, closed at its ends and constructed with a side open'iu g, o4, provided with an inwardly-inclined tongue, c", and the shield e7, placed over the opening or mouth e, and providing a passageway, open at both ends, between it and the pipe e2, substantially as set forth, and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 2d day of April, 1880.

A JOHN v GOPELAND.
